Published: May 24, 2021

The rational design of photocatalysts for efficient nitrogen (N2) fixation at ambient conditions is important revolutionizing ammonia production and quite challenging because the great difficulty lies in adsorption activation inert N2. Inspired by a biological molecule, chlorophyll, featuring porphyrin structure as photosensitizer enzyme nitrogenase an iron (Fe) atom favorable binding site N2 via π-backbonding, here we developed porphyrin-based metal–organic framework (PMOF) with Fe active center artificial photocatalyst reduction reaction (NRR) under conditions. PMOF features aluminum (Al) metal node imparting high stability incorporated atomically dispersed residing each ring promoting N2, termed Al-PMOF(Fe). Compared pristine Al-PMOF, Al-PMOF(Fe) exhibits substantial enhancement NH3 yield (635 μg g–1cat.) rate (127 h–1 82% 50%, respectively, on par best-performing MOF-based NRR catalysts. Three cycles photocatalytic experimental results corroborate stable activity combined theoretical reveal that Fe–N can mitigate rate-determining step NRR. possible pathways were established. Our study MOF will provide insight into catalysts photosynthesis.

Noble-Metal-Free Multicomponent Nanointegration for Sustainable Energy Conversion

Chemical Reviews, Journal Year: 2021, Volume and Issue: 121(17), P. 10271 - 10366

Published: July 6, 2021

Global energy and environmental crises are among the most pressing challenges facing humankind. To overcome these challenges, recent years have seen an upsurge of interest in development production renewable chemical fuels as alternatives to nonrenewable high-polluting fossil fuels. Photocatalysis, photoelectrocatalysis, electrocatalysis provide promising avenues for sustainable conversion. Single- dual-component catalytic systems based on nanomaterials been intensively studied decades, but their intrinsic weaknesses hamper practical applications. Multicomponent nanomaterial-based systems, consisting three or more components with at least one component nanoscale, recently emerged. The multiple integrated together create synergistic effects hence limitation outperformance. Such higher-efficiency will potentially bring additional benefit balance-of-system costs if they exclude use noble metals, considering expense sustainability. It is therefore timely review research this field, providing guidance noble-metal-free multicomponent nanointegration In work, we first recall fundamentals catalysis by nanomaterials, nanointegration, reactor configuration water splitting, CO2 reduction, N2 reduction. We then systematically discuss advances multicomponent-based photocatalytic, photoelectrochemical, electrochemical nanomaterials. On basis further laterally evaluate different integration strategies highlight impacts activity, performance stability, product selectivity. Finally, conclusions future prospects nanointegration. This work offers comprehensive insights into cost-competitive energy-conversion technologies assists researchers working toward addressing global environment.

Metal–Organic Framework Decorated Cuprous Oxide Nanowires for Long‐lived Charges Applied in Selective Photocatalytic CO₂ Reduction to CH₄

Angewandte Chemie International Edition, Journal Year: 2020, Volume and Issue: 60(15), P. 8455 - 8459

Published: Dec. 28, 2020

Abstract Improving the stability of cuprous oxide (Cu 2 O) is imperative to its practical applications in artificial photosynthesis. In this work, Cu O nanowires are encapsulated by metal–organic frameworks (MOFs) 3 (BTC) (BTC=1,3,5‐benzene tricarboxylate) using a surfactant‐free method. Such MOFs not only suppress water vapor‐induced corrosion but also facilitate charge separation and CO uptake, thus resulting nanocomposite representing 1.9 times improved activity for selective photocatalytic reduction into CH 4 under mild reaction conditions. Furthermore, direct transfer photogenerated electrons from conduction band LUMO level non‐excited has been evidenced time‐resolved photoluminescence. This work proposes an effective strategy conversion synergy adsorption, leading enhanced when integrated with metal photocatalyst.
